Question

我是浏览器的新手。我尝试了下面的代码，并在加载我的网页时得到Uncaught ReferenceError: module is not defined。一切都很简单，所以不确定我做错了什么：

chronoOpenList.js：

module.exports = function getChronoOpenList() {
    var xml = new XMLHttpRequest();
    xml.open("GET", "api/nextrequestdue/", true);
    xml.onreadystatechange = function () {
        if (xml.readyState === 4 && xml.status === 200) {
            var jsonText =  xml.responseText;
            parseChronoAndBuildElements(jsonText);
        }
    }
    xml.send(null);
}

main.js：

var getChronoOpenList = require('./chronoOpenList');
getChronoOpenList();

HTML：

<script style="text/javascript" src="{% static 'js/bundle.js' %}"></script>

浏览器的命令：

one@chat-dash /home/git/recognizer/recognizer_project/static/js $ /usr/local/lib/node_modules/browserify/bin/cmd.js main.js -o bundle.js

bundle.js：

(function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);throw new Error("Cannot find module '"+o+"'")}var f=n[o]={exports:{}};t[o][0].call(f.exports,function(e){var n=t[o][1][e];return s(n?n:e)},f,f.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s})({1:[function(require,module,exports){
module.exports = function getChronoOpenList() {
    var xml = new XMLHttpRequest();
    xml.open("GET", "api/nextrequestdue/", true);
    xml.onreadystatechange = function () {
        if (xml.readyState === 4 && xml.status === 200) {
            var jsonText =  xml.responseText;
            parseChronoAndBuildElements(jsonText);
        }
    }
    xml.send(null);
}

....
},{"./chronoOpenList":1}]},{},[2])

Answer 1

我相信你需要：

var parseChronoAndBuildElements = window.parseChronoAndBuildElements;

Answer 2

函数parseChronoAndBuildElements未在getChronoOpenList函数范围内定义。

您需要在该范围内定义parseChronoAndBuildElements，如下所示：

chronoOpenList.js：

var parseChronoAndBuildElements = require('./parseChronoAndBuildElements.js');

module.exports = function getChronoOpenList() {
    var xml = new XMLHttpRequest();
    xml.open("GET", "api/nextrequestdue/", true);
    xml.onreadystatechange = function () {
        if (xml.readyState === 4 && xml.status === 200) {
            var jsonText =  xml.responseText;
            parseChronoAndBuildElements(jsonText);
        }
    }
    xml.send(null);
}

Browserify“模块未定义”
